Peacock fish is one of the most popular small tropical ornamental fish for the majority of new and old ornamental aquarists. In the aquarium market, there has never been loneliness, and the biggest reason is that the peacock fish is like a palette, and the peacock fish basically does not feel bored. Because each generation of newborn peacock fish will surprise us, these surprises are unpredictable, so we are fascinated.
However, in the process of communicating with the aquarists who raise peacock fish during this time in our "Fish Farming", we found that some aqua friends actually do not know how the name of the peacock fish came from, that is, how to hear how people call it, or how to name it for aquarium shop merchants, and follow it. This is prone to an embarrassing situation, that is, after calling a name, the two sides have different perceptions of fish. For example, a chestnut, before a fisherman asked a question, directly asked: Why does Hongyun shrink his fins when he is head? My first reaction was: Luohan fish fins? Later, when I thought about it carefully, I felt that it was not right, and the Luohan fish generally did not shrink their fins. After thinking about it more carefully, I speculated whether it was a peacock fish that was eliminated by the united states that was all red and half yellow on the market, and was named "hong luck", and when I asked, I knew that it was really this peacock fish.
In fact, it is said to be eliminated, but it is also a new variety, because the random distribution of red and white, if the red is just distributed in the head, then it is the head of the good fortune, and it is indeed very image.

Such a thing made me have an idea: whether the name of the peacock fish is not very clear, then this article and everyone simply popularized, how the various colors of the peacock fish come from, and the most grounded is how the peacock fish is named.
First of all, we need to know why the names between different species of peacock fish are so difficult to call, that is, because peacock fish is like a living palette. Each generation of newborn peacock fish inherits the x pair of genes of the previous generation (x refers to the unknown number, that is, the number of inherited genes is unknown), which we can currently understand as random. As mentioned above, it is this unknown uncertainty that gives the peacock fish such a great charm that the peacock fish has been popular in the aquarium circle to this day.
Peacock fish have N many pairs of genes, which are divided into recessive genes and dominant genes. Why is it denoted by "N"? Because there are currently many pairs of genes in peacock fish, we have no past data to study, nor have they been specifically studied. Therefore , " N " is used to represent a very large number of unknowns. This may seem mysterious, and yes, the peacock fish is a mysterious ornamental fish species. Because there are still new peacock fish species coming out, they have too many genes, and the phenotype of different gene pairs is different, so some peacock fish look very similar, in fact, different species.
To briefly mention it again, recessive genes are not easily manifested in the process of reproductive inheritance, such as albinism, which is only manifested when two recessive genes are combined. The dominant gene is a relatively strong gene, as long as there is one can show this state, such as snake stripes, grass tails, mosaics These lines are controlled by dominant genes.

Let's use the peacock fish albino phenotype as an example:
Using the simple knowledge we have learned in high school biology, the uppercase letter A is used to represent the dominant gene (not albino), and the lowercase subtitle a is used to represent the recessive gene (albinism). If the combination of these genes is aa, then the phenotype is recessive, that is, albino. And if the combination of genes is Aa, then the phenotype is dominant, that is, non-bleaching, normal body color. The final result is AA, which is also dominant and does not whiten the normal body color. Why are there fewer albino peacock fish on the market than there are not albino peacock fish? Let's look at the permutations and combinations of the two genes A and A.
First case:
Male fish AA (normal non-albino), female aa (albino), their combined offspring in the performance of the A gene has only one result, that is, Aa, that is, the performance of normal dominant genes, not albino.
The second case:
Male fish Aa (normal not albino), female aa (albino), this situation has two results, the following to make a diagram for everyone to see:
Simulated gene pairing Figure 1
As can be seen from the picture, although there are more a on the surface, there are only two results after this collocation result, Aa and aa, and the probability is the same, one in two.
Third case:
Male fish Aa (normal non-whitening), female fish Aa (normal non-whitening), this pairing method is actually the most typical, the result is four combinations, the same to show you the illustration:
Simulated gene pairing Figure 2
As you can intuitively see from the diagram, the probability of AA appearing in this collocation result is one-fourth, the probability of appearing Aa is one-half, and the probability of appearing aa is also one-quarter. However, according to the dominant and recessive performance of genes, only aa can show albinism, and the phenotypes of AA and Aa are normal and non-albino, so the probability of albinism in such a combination is only one-quarter, that is to say, only 1 of the 4 offspring small fish may be albino.
There is also a fourth and fifth case, the male and female fish are AA or both are aa, this situation is not suspenseful, either the offspring are AA normal non-albino, or the offspring are aa albino.
The above example is just the performance of a set of genes in the peacock fish, as we mentioned above, the peacock fish has N pairs of genes. You can imagine that there are already several possibilities for a single pair of class A genes, so there are so many genes in the peacock fish, how likely it is! There are nearly 200 species of peacock fish that have now been recorded in the atlas, according to incomplete statistics. However, we think that this is only the tip of the iceberg, in the huge gene pool of peacock fish, there is still a huge room for development after 200 species.

Well, the above things may be more complicated, not very in line with our "Fish Farming" consistent style: in an easy-to-understand language, share the grounded fish farming experience. Then let's talk to you about a more practical point, that is, the naming of peacock fish! You can first collect this formula: peacock fish name = special attributes + color + texture + tail type.
1. Special attributes:
Special attributes refer to some of the characteristics of the origin, such as Andras, Sri Lanka, etc., which is an alternative, because many human-bred peacock fish do not have such characteristics.
2、Color:
Color this is easier to understand, generally what color we see with the naked eye is directly added on the good, peacock fish common colors are, red, yellow, blue, green, white, black, more rare colors and purple and pink, as well as some transitional colors.
3. Texture:
The pattern is also very well understood, that is, the lines outside the color seen, such as the spray point of the grass tail, the mysterious pattern of the mosaic, the snake pattern of the snake king gene, and so on.
4. Tail type:
Tail type is also clear at a glance, the general common tail type is a fan tail (or triangular tail), a sword tail (upper sword tail and a lower sword tail), a piano tail, it is worth mentioning that the fan tail is the most common, so it is generally ignored, only the sword tail and the tail will be added to the name.
Next, we use a few examples to name, the first picture, all red peacock fish, because there is no pattern on the body, but also a fantail, so it is simply called full red peacock fish. In addition, if the albino species or yellowing species of all-red peacock fish are directly called albino all-red peacock fish, or yellowed full-red peacock fish.
All red peacock fish
Looking at this picture again, the name of this peacock fish is: ribbon blue grass tail peacock fish, which is the classic naming, the special performance of the ribbon, because the pectoral fin drawing is very long, this we call "ribbon", blue is the main color of the body, the grass tail is the spray point of the tail, and finally the "piano tail" is a special tail performance.

Well, this is about some of the knowledge that needs to be deeply understood on the peacock fish, as well as a simple naming method, and you can just apply this naming formula. If you still have any doubts, please leave a message in the comment area to discuss together.
Here is the fish farming said, if you also like to raise ornamental fish, do not put hands-on point to pay attention, all the fish farming to know is here!
